Attention :
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
 
 
Q & A:
 
Q : Why output voltage is less than the nominal voltage
A : Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very low
 
Application :
Packing list does not include USB Charger/routers/mobile power
Modify Parameter Description:   
 
1.4A current limiting resistor,Remove the resistance, the maximum input current can reach 2A.
But IC have "Over Temperature Protection" Function.It will turn off the power MOSFET automatically when the internal junction temperature is over 150 Degrees Celsius. The power MOSFET wake up when the junction emperature drops 30 Degrees Celsius under the OTP threshold temperature
The master chip is FP6291(Made in Taiwan)
